NEW EVIDENCE FOR AND NEW REACTIONS OF ORTHO-LITHIO YLIDS

While α-lithio ylid 2 may be generated from triphenylphosphonio-bromomethylid through halogen/metal exchange, the reaction of triphenylphosphonio-methylid 1 with sec- or tert-butyllithium produces nearly quantitatively the o-lithio ylid 3, which is stable at -60 deg C but slowly decomposes at higher temperatures via a cyclization product 5 to give the α-lithio phosphine 4.
